Tetrachloroethane

Tetrachloroethane

(or 1,1,2,2-tetrachloroethane), a symmetrical tetrachloroethane, CC12H—CC12H; a colorless liquid with an odor similar to that of chloroform and with a boiling point of 146.2°C and a density of 1.597 g/cm3 at 20°C. Tetrachloroethane dissolves in organic solvents; it readily dissolves phosphorus, sulfur, fats and oils, resins, and many other organic and inorganic compounds, but its use is limited because of its toxicity (it is a powerful renal and liver toxin). The maximum allowable concentration of tetrachloroethane vapor in air is 0.001 mg perliter. Tetrachloroethane, which is produced by the chlorination of acetylene, HG≡CH, is used mainly for the production of trichloroethylene.

Associations of ASD with styrene, butadiene, and tetrachloroethane were elevated for boys and not girls, whereas the association of ASD with mercury compounds were elevated for girls and not boys (Kalkbrenner et al.

7) While PDB was the only chlorine-containing compound to be found a priority hazard, there were lots of chlorine containing chemicals lower down on the list including hexachlorobutadiene, benzyl chloride, vinyl chloride, methylene chloride, tetrachlorothene, dichloropropane, tetrachloroethane, dichloroethane, trichloroethene, and, of course, chlorine.

The Sheldon-Arleta Landfill has the following toxic wastes in it, based on the city of Los Angeles' own reports: benzene, chlorobenzene, dichlorobenzene, methane, tetrachloroethane, toluene, vinyl chloride and xylene.

In addition to methane and TNMHC, 16 hydrocarbon species were selected and used to calculate percent control efficiency including freon, methylene chloride, 1,1,1-trichloroethane, tetrachloroethane, trimethylbenzenes, 1,4-dichlorobenzene, toluene, xylenes, and ethylbenzene.
